mathematicsMATLAB

 p = [30 30 30 30 30 30 0 0 0 0 0 0 0 0 30 30 30 30 30 30]
I want to swap it like [30 30 30 30 30 30 30 30 30 30 30 30 0 0 0 0 0 0 0 0];
 Np = length(M);
   for p = Np/2: -1:2
        for CP = p-1:-1:1
            if M(1,CP) ~= M(1,CP+1) 
                M(1,CP) = M(1,CP+1)
            end
        end
   end
